3 Use layers and groups

One of the main benefits of vector illustrations is that you can easily edit and modify them, without losing quality or resolution. However, to make the most of this feature, you need to organize your vector artwork using layers and groups. Layers and groups allow you to separate different elements of your illustration, such as the background, the foreground, the characters, and the details. This way, you can work on each element individually, without affecting the rest of the illustration. You can also use layers and groups to apply effects, filters, and masks, to create different looks and moods for your illustrations.

4 Master the pen tool

The pen tool is one of the most important and versatile tools for creating vector illustrations, as it allows you to draw curves and shapes with precision and control. The pen tool works by creating anchor points and handles, which you can adjust to modify the direction and curvature of your paths. You can use the pen tool to create outlines, fillings, strokes, and patterns, as well as to trace over your sketches or existing images. To master the pen tool, you need to practice and experiment with different settings, such as the stroke width, the corner and cap options, and the smoothness and fidelity options.

5 Add texture and depth

Vector illustrations can sometimes look too flat and smooth, especially if you use a lot of solid colors and shapes. To add some texture and depth, you can use gradients and transparencies to create subtle variations in color and light, as well as shadows and highlights. You can also use brushes and patterns to create organic shapes and textures, such as fur, hair, grass, or wood. Additionally, you can apply textures and images to your vector shapes with clipping and masking, without altering their original form. For example, you can clip a photo of a fabric to a vector shape of a dress or mask a vector shape of a cloud with a texture of a sky.

6 Experiment and have fun

The last and most important technique for creating vector illustrations in children's books is to experiment and have fun. Vector illustrations offer endless possibilities for creativity and expression, so you should not be afraid to try new things and explore different styles and techniques. You can also learn from other vector illustrators, by studying their work and finding inspiration from their choices. The more you practice and enjoy creating vector illustrations, the more you will develop your own unique voice and vision as an illustrator.
